It is caused by pathogenic variants in the iron-responsive element (IRE) of the FTL gene, leading to dysregulated L-ferritin synthesis. Methods: We evaluated a 12-year-old Czech girl with markedly elevated serum ferritin identified incidentally during workup for abdominal pain. Clinical assessment included biochemical, radiological, ophthalmological, and genetic testing of the proband and available family members. Results: Magnetic resonance imaging excluded systemic iron overload, while ophthalmological evaluation revealed bilateral cataracts. Family history indicated multiple affected relatives across three generations. Genetic testing confirmed a heterozygous FTL c.-168G&gt;C variant. Additional screening for common HFE variants revealed heterozygous H63D in several family members, with no impact on ferritin or hepcidin levels. Beyond this case, we provide a comprehensive review of HHCS, including molecular mechanisms, an updated overview of reported FTL mutations, and ophthalmological features that distinguish HHCS cataracts from other congenital cataracts. Conclusions: This report underscores the translational relevance of combining molecular diagnostics, clinical evaluation, and family screening to improve recognition and management of HHCS, and to prevent misdiagnosis and unnecessary iron-depletion therapy.<\/jats:p>","DOI":"10.3390\/genes16111381","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T12:57:13Z","timestamp":1763038633000},"page":"1381","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical and Molecular Clues to Diagnosing Hereditary Hyperferritinemia-Cataract Syndrome: Case Report and Literature Review"],"prefix":"10.3390","volume":"16","author":[{"given":"Barbora","family":"Ludikova","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine and Dentistry, Palacky University and University Hospital Olomouc, 779 00 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1737-8125","authenticated-orcid":false,"given":"Lucie","family":"Sochorcova","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Medicine and Dentistry, Palacky University, 779 00 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damjan","family":"Jaksic","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, T.
